The invention relates to a semitrailer with rear wheels capable of achieving an electronic differential and a reversing method. The semitrailer comprises an ECU, a differential knob, a visual positioning system and a front wheel power-assisted steering mechanism, and a pair of wheels at the rearmost end of the semitrailer are two electric wheels capable of being independently driven; the differential knob can input different rear wheel differential numerical values to the ECU; the visual positioning system comprises a visual identification camera installed at the rear end of the semitrailer, the ECU can receive information of the visual identification camera and generate an electronic map, a displayer is arranged in a cab of the semitrailer, and the displayer can display the reversing track of the semitrailer in the electronic map under any differential numerical value within a set range; and the ECU can calculate the corresponding front wheel deflection angle according to a differential signal and the preset rotating speed of the inner side electric wheel, and steering of the front wheel is achieved through the front wheel power-assisted steering mechanism.

    本公开涉及一种后轮能够实现电子差速的半挂车辆及倒车方法,包括ECU、差速旋钮、视觉定位系统和前轮转向助力机构,半挂车最后端的一对车轮为两个能独立驱动的电动轮;差速旋钮能够向ECU输入不同的后轮差速数值;视觉定位系统包括安装在半挂车后端的视觉识别摄像头,ECU能够接收视觉识别摄像头的信息并生成电子地图,半挂车辆的驾驶室中设有显示器,所述显示器能够显示在设定范围内任意差速数值下,半挂车辆在电子地图中的倒车轨迹;ECU能够根据差速信号以及预设的内侧电动轮转速来推算出对应的前轮偏角,并通过前轮转向助力机构实现前轮的转向。
